Steam Mobile Authenticator

This is a group for people who use Steam Mobile Authenticator.

The Steam Guard Mobile Authenticator is a feature of the Steam Mobile App that provides an additional level of security to your Steam account. The authenticator generates a code that you need to enter every time that you log on to your Steam account. The code changes every 30 seconds, can be used only once, and is unguessable.

This system (commonly called two-factor authentication) is stronger than just your username and a password.

Valve also strongly recommends that you add a phone number to your account, which makes recovering your account quite a bit easier, should you lose access.

Your phone does not need to be connected to the Internet for the authenticator to work (however, your phone does need to know the correct time).
